Scientists think they solved the mystery of the Amaterasu particle
Astrophysicists suggest that ultrahigh-energy cosmic rays, such as the 'Amaterasu particle,' may consist of atomic nuclei heavier than iron. This theory explains how these particles can travel across intergalactic space without losing their extreme energy levels.
Why it matters
Solving the mystery of high-energy cosmic rays helps scientists better understand the most powerful and violent phenomena in the universe.
An ultraheavy particle may help explain one of the most puzzling mysteries in modern astrophysics: the origin of the most energetic particles ever detected.
The article provides a neutral, scientific explanation of a complex astrophysical theory.
